[jbosstools-issues] [JBoss JIRA] (JBIDE-27083) Process management for running odo cli instances

Process management for running odo cli instances ------------------------------------------------ Key: JBIDE-27083 URL: https://issues.redhat.com/browse/JBIDE-27083 Project: Tools (JBoss Tools) Issue Type: Enhancement Components: openshift Affects Versions: 4.14.0.Final Reporter: Jeff MAURY Assignee: Stephane Bouchet Priority: Major Fix For: 4.15.0.Final While working on the odo based explorer to JBoss Tools, I noticed that we are starting long running process and those processes are not managed / controlled once launched. I think we should do and I will explain my proposition. The long processes are the following: * watch * follow log * debug Less critical , we also have describe, list services and component and in general each time we launch odo in a terminal. This is less critical because they are less long living. The problem that we have is: * we should stop them when context is switched * we should stop them when tooling stops (seems VSCode is handling that properly) * we should stop them when we undeploy/delete a component Another plus is that managing them will prevent multiple executions of the same task and control of state for the debug. Here is my proposition: each time we start a long running process we keep it at the OdoCli (for JBoss Tools / IJ) level in a map that is keyed by project / application / component / action-type. Then, we can: * while processing delete / undeploy, scan the map to find proper processes to stop * while processing debug we can check that debug is already running or not * for cleanup before tooling exit or context switch we should add a reset method (this is required btw for proxy support as we need to recompute the HTTPS_PROXY env variable that will be passed to future odo executions
